Holy shit, ATT 3B2, I haven't heard any mention of those in a long time.
So, six years later, in 1994, I found myself as the UNIX system administrator for a large (at the time) datacenter at Keesler Regional Medical Center, Keesler AFB, Biloxi Mississippi, where we had quite a number of 3B2s. They were, in fact, the only machines we had that were rated for classified data.
If memory serves, they ran AT&T System V release 3 UNIX.
We also had, among others, DGUX, SCO, AOS/VS, Sun and Vax/VMS servers. Of course each of AOS/VS and VMS had their own, non-UNIX operating systems.
Funny story: we put word out to AETC (Air Education and Training Command) that we needed more 3B2s, and a few months later, some pallets arrived from Homestead Air Force Base, which had been destroyed by hurricane Andrew a couple of years prior. These servers had green and brown smears on them. Clearly they had been submerged by hurricane flooding for some period of time. So we ran a long extension cord out to the parking lot, plugged them in and stepped back. Much to our surprise, several of them actually worked, and later ended up racked in our datacenter.
- downerending 7y agoHa. I miss the days when you didn't have to worry about your Unix box blowing away in a hurricane.
- jes 7y agoFor what it's worth, I also used DG/UX, MV/UX and AOS/VS on Data General equipment (MV/10000, MV/4000) at the University of Washington in the 1985ish time-frame. I remember porting many BSD 4.x utilities to MV/UX. What a learning experience, with the MVs differently-formatted byte vs. word pointers. The C compiler was really nice, though. Fun times.
- Diederich 7y agoYou might be the first person I've run into that has heard of AOS/VS. I've run into one other person over the years that has heard of DG/UX. Good times indeed.
- coolgeek 7y agoMy first Unix experience (~1993) was in a heterogeneous shop doing electronic pre-presss. SunOS 3.5 on OEM PDP-11s. SunOS4.1.4 on SPARC Stations. SunOS5 (Solaris) on SPARC Stations. DG/UX on a pizza box. SCO on (I think) a 386
- gjm11 7y ago> ATT 3B2 There are a number of papers in pure mathematics authored by Doron Zeilberger and Shalosh B Ekhad. (See https://sites.math.rutgers.edu/~zeilberg/ekhad/papers.html https://sites.math.rutgers.edu/~zeilberg/ekhad/papers.html for a list. I don't think it's exhaustive) Shalosh B Ekhad is Zeilberger's computer, which once upon a time was an AT&T 3B1. In Hebrew, 3 is "shalosh" and 1 is "ekhad". (The 3B1 isn't actually much like the 3B2, despite the very similar names.)
